As School Threats Proliferate, More Than 700 Students Are

Earlier this month, a detective knocked on Shavon Harvey’s door, in suburban Ohio, to ask about her son. The son had sent a Snapchat message from her phone to his friends, saying there would be shootings at several schools nearby.

She rushed to the police station, where her son was already in custody, but the police did not release him. He was charged with inducing panic, a second-degree felony, and officials kept him in detention for 10 nights.

He is 10.

Ms. Harvey’s son is far from the only child arrested this month after similar behavior. And he’s not even the youngest.

In the three weeks since two teachers and two students were killed at Apalachee High School in the deadliest school shooting in Georgia’s history, more than 700 children and teenagers, including at least one fourth grader, have been arrested and accused of making violent threats against schools in at least 45 states, according to a New York Times review of news reports, law enforcement statements and court records. Almost 10 percent were 12 or younger.

The arrests come as the police and schools confront an onslaught of threats of violence, gunfire and bombings. The reports have terrified students and their parents, caused attendance to plunge and forced the temporary closure of dozens of campuses. Some schools have canceled homecoming parades, middle school dances and Friday night football games.
